RESUMO
Objective Multiple software applications and systems and complex hardware are utilized in the process of radiotherapy. In this paper,Xenapp-based visualized system was adopted to integrate each system during the radiotherapy procedures. Methods Windows2008r2 operating system,Citrix Xenapp 6. 5 sp1 enterprise edition,sqlserverr2008 express database were utilized. The Xenapp server was installed and the commonly used software applications were installed and published on this server. CitrixReceiver was installed on the computers in the local network in Department of Radiotherapy. A web browser was utilized to log in the Xenapp server to access all the applications published on the server. Results The application of Citrix Xenapp-based virtualized system significantly reduced the cost of computer hardware by more than 50％,decreased the maintenance cost of technical personnel. Besides,it made the process of Department of Radiation Oncology seamless and improved the efficiency of the staff in the Department of Radiation Oncology. Conclusions The Xenapp-based virtualized system can save cost and improve efficiency in the process of radiotherapy,which is worthy of widespread application in clinical practice.
